title: Primary chondrosarcoma of breast.
abstract: Mammary sarcomas are heterogeneous group of malignant neoplasms that arise from the mammary stroma. They are uncommon tumours and most of these occur as a component of other tumours. Of the malignant breast mesenchymal tumours, pure sarcomas which lack epithelial component are rarer as these comprise only 0.5% of the breast tumours. Of these, the most common are angiosarcomas, liposarcomas and osteosarcomas. Pure, primary and De novo chondrosarcomas features as one of the rarer types of sarcomas of breast and should be differentiated from Phylloides tumours with chondromatous areas by extensive sampling which also excludes ductal elements in the tumour. This case report describes very rare primary breast sarcoma i.e. chondrosarcoma in a female aged 40 years which was treated by simple mastectomy.
